14、ional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has bee
15、n established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stand
16、ardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
17、 voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all
18、 such patent rights. ISO 22840 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. BS ISO 22840:2010ISO 22840:2010(E) ISO 2010 All rights reserved vIntroduction Extended-range backing aids (ERBA) are detection devices with non-contact sensors that assist the driver during
19、low- to mid-speed backing manoeuvring. These systems detect and warn the driver of objects in the pathway of the vehicle. In comparison to low-speed-only devices whose main purpose is assisting in parking manoeuvres (e.g. ISO 17386), the purpose of the ERBA is to assist in higher-speed backing manoe
20、uvres associated with traversing longer distances. BS ISO 22840:2010BS ISO 22840:2010INTERNATIONAL STANDARD ISO 22840:2010(E) ISO 2010 All rights reserved 1Intelligent transport systems Devices to aid reverse manoeuvres Extended-range backing aid systems (ERBA) 1 Scope This International Standard fo
21、r extended-range backing aids (ERBA) addresses light-duty vehicles e.g. passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded) equipped with such ERBA systems. This International Standard establishes minimum functionality requirements that the driver can expect
22、of the system, such as the detection of and information on the presence of relevant obstacles within a defined detection range. This International Standard also sets minimum requirements for failure indication as well as performance test procedures. This International Standard includes rules for the
23、 general information strategy but does not restrict the kind of information or display system. ERBA systems are intended to provide backing aid functionality over an extended area located aft of the subject vehicle. ERBA systems are not intended for short-range detection of obstacles located immedia
24、tely behind the vehicle. If a short-range detection system is needed, either in lieu of or in addition to an ERBA system, reference can be made to ISO 17386. This International Standard does not include reversing aids and obstacle-detection devices for use on heavy commercial vehicles. Requirements
25、for those systems are defined in ISO/TR 12155. This International Standard does not include visibility-enhancement systems, such as video-camera aids that do not have distance ranging and warning capabilities. ERBA systems use object-detection devices (sensors) for detection and ranging in order to
26、provide the driver with information based on the distance to obstacles. The sensing technology is not addressed; however, technology does affect the performance test procedures defined in this International Standard. The test objects are defined based on systems using ultrasonic and radar sensors, w
27、hich are the most commonly used detection technology for long-range applications at the time of publication of this International Standard. ERBA systems are intended to supplement the interior and exterior rear view mirrors, not eliminate the requirement for such mirrors. Automatic actions (e.g. app
28、lying brakes to prevent a collision between the subject vehicle and the obstacle) are not addressed in this International Standard. Responsibility for the safe operation of the vehicle remains with the driver. ERBA systems calculate a dynamic estimate of collision danger e.g. perhaps using a time-to
29、-collision, (TTC) algorithm and warn the driver that immediate attention is required in order to avoid colliding with the detected obstacle. A dynamic warning is necessary for the higher vehicle speeds that occur in backing events where the relative closing velocities between the vehicle and the obs
30、tacle are greater as compared to low-speed situations, such as parking. The purpose of this dynamic warning is to deliver a more urgent warning to the driver in order for the driver to take timely action. Distance indications are optional, but if so included, it is recommended that reference be made
31、 to ISO 15008 for requirements.

It is not intended to reliably detect pedestrians or a
47、nimals. It is recommended that the vehicle operators handbook (owners manual) include an advisory note that clearly indicates this limitation. 5.1 Steering angle As a minimum requirement, the ERBA system shall support straight backing manoeuvres. The azimuth zone-of-regard definition (3.6) in this I
48、nternational Standard relates to this primary-use case. See Figure 1. ERBA systems may adapt to the steering angle for better detection of obstacles in the path of travel in curves; however, this International Standard does not include performance requirements for systems that adapt to steering angl
49、e. The requirements of this International Standard shall be fulfilled during backing events with the steering in the neutral position. 5.2 Detection range ERBA systems shall detect targets located in the 1,0 m to 5,0 m range located behind the vehicles rear bumper in a region called the zone of regard. See Figure 1. ERBA systems may detect targets closer than 1,0 m, however, this International Standard does not include performance requirements for this range. NOTE It is proposed that sy
